LG 75UH5N-M 75-inch UHD Signage Display

Overview

The LG 75UH5N-M is a 75-inch UHD (3840 x 2160) signage display built for continuous business use, rated for 24/7 operation with 500 nit typical brightness and an anti-glare screen. It has built-in webOS 6.0 with 16GB storage, so content can run without a separate media player, plus two USB ports, three HDMI inputs and a DisplayPort. Suited to Qatar offices and schools.

What the LG 75UH5N-M is built for

The LG 75UH5N-M is a 75-inch UHD signage display from the UH5N series, designed for continuous commercial use. Its 3840 x 2160 panel carries four times the pixel count of Full HD, so menus, floor plans and small text stay sharp at close range. It is rated for 24/7 operation, which suits lobbies, corridors and classrooms that run through long daily schedules.

Typical brightness is 500 nit with a 1,200:1 contrast ratio. The anti-glare surface, rated at 25% haze, reduces reflections from windows and ceiling lights, which helps in bright reception areas. A 178 x 178 viewing angle keeps the picture readable for people standing beside the screen.

Playback and sensors without an extra media player

A high-performance processor running webOS 6.0 handles several tasks on the display itself, so many installations do not need a separate media player. The 16GB internal memory holds local content, and local scheduling lets you plan what plays and when. Built-in Wi-Fi and Bluetooth sit alongside an RJ45 LAN port for wired networks. A temperature sensor, an IR auto brightness sensor and a gyroscope are also fitted. The panel works in portrait or landscape orientation, with an even 12.9 mm bezel on all four sides.

Ports and control for meeting rooms and signage networks

Three HDMI inputs at 3840 x 2160 and 60Hz, HDCP 2.2/1.4
One DisplayPort input at 3840 x 2160 and 60Hz
Two USB 2.0 Type A ports for drives and peripherals
RJ45 LAN, RS232C in and out, IR in and audio out
Two built-in 10W speakers

The two USB ports let a presenter open a presentation from a memory stick while a keyboard or mouse stays connected to the second port. RS232C and IR daisy chaining through the control ports allow one source to manage several units.

Where a 75-inch display suits Qatar sites

A private school in Al Wakrah fitting out a ground-floor corridor could use this panel for timetables, achievement boards and visitor messages, with content updated across the building. A clinic in Al Sadd might run patient information and queue notices in its waiting area, indoors and inside the air-conditioned zone. A boardroom in West Bay or The Pearl could use the 75-inch screen for shared documents and video calls.

Several units can form a video wall, as tile mode supports layouts up to 15 by 15 panels. That suits a retail frontage in Lusail or a feature wall in a head office lobby.

What to plan before ordering

The head weighs 35.7 kg and 44 kg packed, so plan for two people to lift it and check the wall structure before fixing. The VESA pattern is 600 x 400, and the optional LSW640A/B wall mount is available. SmartRooms Qatar offers free site surveys, which we recommend before wall-mounting a panel this size.

The display operates between 0°C and 40°C at 10 to 80% humidity. Qatar summer heat outdoors regularly passes 45°C, so keep this model in an air-conditioned indoor space and confirm the environment with our team during quotation. Power is AC 100 to 240 V at 50/60 Hz, with typical consumption of 160W and a maximum of 247W.

Government ministries, schools and companies can order through a purchase order or LPO, and SmartRooms Qatar delivers to all eight municipalities. Request a quote for the LG 75UH5N-M today, and our team will send a quotation, usually within one working day.

Questions about 75UH5N-M

What is the LG 75UH5N-M best suited for?

The LG 75UH5N-M suits organisations that need a large, always-on screen for information, signage or presentations. Its 75-inch UHD panel is rated for 24/7 operation and has 500 nit typical brightness, which makes it practical for school corridors, clinic waiting areas, reception areas and meeting rooms in Doha, Lusail and Al Wakrah. If viewers sit close to the screen, compare it with smaller models before deciding.

Do I need a separate media player to show content?

Not for many setups. The LG 75UH5N-M runs webOS 6.0 on a high-performance SoC, so it can play content and perform several tasks on its own. It has 16GB internal memory for local content and supports local scheduling. For centrally managed networks, it is compatible with SuperSign CMS and SuperSign Cloud. Ask the SmartRooms Qatar team to review your content volume and network design before ordering.

Can it run 24/7 in a lobby in West Bay or elsewhere in Doha?

It is rated for 24/7 operation, with an operating range of 0°C to 40°C and 10 to 80% humidity. Qatar summer temperatures outdoors can exceed 45°C, so install it in an air-conditioned indoor lobby, away from direct sunlight and outdoor doors. Do not place it outdoors. Confirm the room temperature and airflow with the SmartRooms Qatar team before approving the quotation.

What picture quality does the panel offer?

The panel has a native 3840 x 2160 UHD resolution, 500 nit typical brightness, a 1,200:1 contrast ratio and 1.07 billion colours (8-bit with FRC). Colour gamut is BT709 95%, with an 8ms response time (G to G) and a 60Hz refresh rate. The anti-glare surface has 25% haze, and the viewing angle is 178 x 178 degrees.

Can presenters use USB drives in meetings?

Yes. The display has two USB 2.0 Type A ports. A presenter can open presentation files from a memory stick while a keyboard or mouse stays connected to the second port, which avoids swapping laptops in a boardroom. USB Plug & Play is supported. Because the ports are USB 2.0, test large video files before the meeting to confirm they load smoothly.

How many devices can I connect to it?

The LG 75UH5N-M has three HDMI inputs supporting 3840 x 2160 at 60Hz with HDCP 2.2/1.4, one DisplayPort input, one RJ45 LAN port, RS232C in and out, IR in and audio out. It also has two USB 2.0 Type A ports. For a classroom with a laptop, a document camera and a media player, the three HDMI inputs cover most common sources.

Can it be wall mounted, and what should we plan for?

Yes. The VESA mount pattern is 600 x 400, and the optional LSW640A/B wall mount is available. The head weighs 35.7 kg and 44 kg packed, so the fixing must be rated for that load and two people should lift the panel. SmartRooms Qatar offers free site surveys, which we recommend before fixing to any wall, particularly partition walls in newer buildings.

Can it be used in portrait orientation?

Yes. The panel supports both portrait and landscape orientation. Its bezel is 12.9 mm on all four sides, so the picture looks even when rotated, which suits menu boards, directories and wayfinding in a mall or hospital corridor. Screen Rotation and External Input Rotation are both supported. Confirm the mount and cable routing for portrait use before ordering.

Which content management software works with it?

The data lists compatibility with SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud, Mobile CMS and Connected Care. It also supports Crestron Connected, SNMP and Wake on LAN for remote monitoring. SuperSign Cloud suits organisations with several sites, such as a school group or a company with offices across Doha and the industrial areas. Ask the SmartRooms Qatar team which version fits your network.

Does the on-screen menu support Arabic?

Yes. The on-screen language list includes Arabic, alongside English, French, German and many others. This helps offices in Qatar that work in Arabic and English side by side, such as government offices and schools. Choose the language during setup, and confirm the set-up requirements with the SmartRooms Qatar team before installation.

What power does it need in Qatar?

The built-in power supply accepts AC 100 to 240 V at 50/60 Hz, which covers Qatar's 240 V mains. Typical power consumption is 160W and the maximum is 247W. A smart energy saving setting is listed at 112W, and power-off draw is 0.5W. Plan a socket close to the mounting point, and ask the team to check cable routing during the site survey.

Can several units form a video wall?

Yes. The tile mode setting supports layouts up to 15 by 15 panels. That suits a retail frontage, an airport waiting area near Hamad International or a bank lobby. Plan the mounting, bezel alignment and cable routing for every unit from the start. The even 12.9 mm bezel helps the wall look clean, but the final layout should be confirmed in a site survey and quotation with SmartRooms Qatar.
